Mobile product development · Stacknyu
Build an app that connects to the business behind it.
We build mobile experiences together with the backend and operational tools they depend on. From bookings and memberships to field workflows, the app should work as part of one product.
Selected project
- A development team, not a self-serve tool
- Real products you can inspect
- No complete specification needed

Discuss this projectHow we start
A clear next step. Not a sales maze.
-
Tell us what needs to change
Describe the product or workflow, who uses it, and what is getting in the way. A few sentences are enough to start.
-
Work through the constraints
We review the users, existing systems, integrations, and deployment requirements with you before recommending an approach.
-
Agree the scope before the build
If there is a fit, we define the delivery stages, responsibilities, and estimate for your project. No invented timeline before we understand the work.
Let's make it real
Tell us what you need to build.
What should the software do, who will use it, and what is difficult today? Share enough context for a useful first conversation.
Good software starts with an honest fit.
Good fit
- You need a team to design and build a working product.
- Your roles, workflows, or integrations do not fit a generic tool.
- You can involve someone who understands the business and its users.
Not a fit
- An existing product already solves your problem without significant workarounds.
- You are looking for a ready-made subscription, a template, or a job opening.
Before you enquire
Questions & answers
Are you a software agency or a ready-made software product?
Stacknyu is a development team. We design and build software for your business rather than sell access to a general-purpose tool. We also operate our own products, but this enquiry is for a development project.
Do I need a complete specification before contacting you?
No. Start with the users, the problem, your current process, and any constraints you already know. We can discuss the missing details before deciding whether to scope a project.
How much will the project cost, and how long will it take?
That depends on the workflow, integrations, data, platforms, and delivery scope. We establish those boundaries before providing an estimate. A short project brief is a starting point, not a commitment to a build.
Can you build both the app and its backend?
Yes. Our published projects include connected web, iOS, and Android experiences using shared platform data. We scope the app, backend, integrations, admin controls, and release responsibilities together rather than assume the interface is the whole product.
